So been replaying my New Vegas ultimate edition for my third playthrough and last time I played was only a few days ago, I go to turn it on today and I had a 16mb update. After the update when I got to the main menu I had a message that popped up and said "new content has been added. The game requires a restart" and an option to restart the game. Did so and loaded up my recent save. Nothing, seems out of the ordinary? And all my stuff is the same.

I've played a bunch of times and obviously have all the dlc downloaded. But the crazy thing is there is no news anywhere of this update.

So does anyone know what it is?
